Nike installed the full-length Zoom Air unit in the Cushlon foam midsole, which brought a noticeable popularity to Pegasus. Men's Pegasus is also great for cruising when the Pegasus glows at high speeds. Cushlon foam is stronger than other running shoes in the same category, but it provides sufficient cushioning so you won't feel defeated when running long distances. There is a lot of rubber on the outsole for traction, but Nike still keeps Pegasus lightweight. Not bad for a durable daily trainer. Pegasus can be used for daily training and occasional marathons. The latest version is Nike Air Zoom Pegasus 36.
